fix(inventory): merge draft + list watch into one subscription

Browse source 
InventoryCubit subscribed to watchInventory() and watchDrafts()
separately — two overlapping StreamGroups (both watching attachments)
re-emitted in a tight loop that starved the event loop and hung widget
tests' pumpAndSettle for 10+ minutes (home/inventory/quick-add all
timed out). Replace both with a single watchInventoryView() stream that
loads the catalogued list and the draft tray from one StreamGroup.

Full widget suite no longer hangs: 165 pass. One unrelated failure
remains in the v8 variety edit sheet (Save button pushed off-screen by
new fields).
